DMR Functions in Framework Manager. «on: 18 Nov am». Hello Folks, I am working on Cognos BI version, I have created a DMR model. Hi khayman, Ya, I am new to dimensional functions. I have to add simple ancestor() and Bottoncount() functions. I create a data item is. Could you please suggest how to achieve this scenario using DMR model. * Regards, DMR Function to get Previous Year Data. 6. Answers. 0 .

Posted by Charles Yin at Option 1 handles DMR relative time at database level. Create a query object to host Relative Time. RelativeTime values ‘YTD’, Hi with alternative 2, do I need to update the dates in the parameter map every month? The solution will be demonstrated by using Cognos version To resolve this issue, this option is to provide a solution without change time dimension.
The key point is to define a filter for each relative dimension. Option 3 handles DMR relative time at Report level. Add an indicator in both database layer and business view layer.
Option 3 handles it at report level: All three relative time is mapped as below. The tail function returns a member set. Without applying any changes in database and framework manager, you can dynamically figure out current date, and then apply MDX time functions to determine all periods as requested on the fly. Option 2 handles DMR relative time at framework manager level. Create a new table to host relative time as below. This approach is relatively flexible, and it is easy to use for report authors as well.
There are three relative time frames: RelativeTime Parameter varchar 10Value int. Please see query below.
For Rolling 13 Months. It is most flexible solution, however, it request report authors to have good understanding of MDX functions. This approach is not flexible, as you need to add column into database, but it is very easy to use for report authors.
The main disadvantage of option 1 is to change database when adding a new relative time. Instead of creating column for time dimension, a relative time table is created.
Another key pint is to define top level member, somehow you need to add a reference of date dimension, so that the query engine know to apply the filter of the used dimension. Get the set of members from the Time dimension at the Date level.
The value is actually a month key. Newer Post Older Post Home.

This is a way to develop relative time based report without changing database and framework manager. At the same time, create all relative time dimensions at dimension layer. Returning a member is important if you want to use this data item in another dimensional function.
Please note that you can define more complicated table, such as begin date, and end date.

Now create each relative time as a separated dimension. When published, package looks as fellows. Because the desired result is a single member, the item function is used passing 0 as its index value argument to return only the current period member.
Option 2 handles it at framework manager level: RelativeTime values ‘R13M’, The options above provide report user a clear framework manager model, however functkons need to change database or framework manager.

The dognos is to create a new relative time table. To explore the similar relative time functionalities in cube, this document is intended to provide three solutions to handle relative time, listed below: Add additional relative time flag columns in Time dimension, and update it on daily basis.
Then bring all three highlighted members into report query or report. When published, the package should be displayed as follows. When changing relative cmr, you only need to add record s. Then make time filter dynamic based on relative time table. Get the last date that has data. Fjnctions there is any change for relative time, you need to only add records. In order to explain the concept, the following report is used.
Based on this query, you can create a dynamic parameter map.
